WebFeb 17, 2024 · The np.argmax () function takes two arguments as a parameter: arr: The array from which we want the indices of the max element. axis: By default, it is None. But … In kMaX-DeepLab, we further simplify the spatial-wise softmax to cluster-wise argmax (i.e., applying the argmax operation along the cluster centers). We note that the argmax operation is the same as the hard assignment (i.e., a pixel is assigned to only one cluster) used in the k-means clustering algorithm. camping wolfsmühle gmbh \u0026 co. kg
